Cells Tissues & Organs Crossword - WordMint - Free Printable

Let's solve this crossword puzzle step by step based on the clues provided. The theme is "Cells, Tissues & Organs", so we'll use biological terminology.

Across Clues:

6. Groups of cells with similar functions
→ This is tissue.
✔ Answer: Tissue

7. Cells need food, water and ___ to live
→ Cells require oxygen for respiration.
✔ Answer: Oxygen

9. Groups of tissue with the similar functions
→ This is an organ.
✔ Answer: Organ

11. Tissue that stretches and contracts to let the body move
→ This is muscle tissue.
✔ Answer: Muscle

13. Tissue that receives and carries impulses to the brain and back of the body
→ This is nervous tissue.
✔ Answer: Nervous

14. Outer covering of a cell
→ This is the cell membrane.
✔ Answer: Membrane

15. Contains smaller structures that perform cell functions
→ This refers to the cytoplasm (which contains organelles).
✔ Answer: Cytoplasm

Down Clues:

1. Tissue that covers internal and external body surfaces
→ This is epithelial tissue.
✔ Answer: Epithelial

2. Examples of organs are the heart, brain, liver, ____ and kidneys
→ Missing organ: lungs or stomach? But common ones include lungs.
But "liver, _____ and kidneys" — likely lungs or pancreas. However, most standard lists include lungs.
Wait — perhaps it's stomach? Let’s think: heart, brain, liver, lungs, kidneys — yes.
✔ Answer: Lungs (most likely)

Alternatively, could be intestines, but lungs fits best in sequence.

✔ Answer: Lungs

3. Thread-like structures in the nucleus
→ These are chromosomes.
✔ Answer: Chromosomes

4. You need a ____ to study cells
→ A microscope.
✔ Answer: Microscope

5. Tissue that anchors, connects and supports other tissue
→ Connective tissue.
✔ Answer: Connective

8. Controls the traits children inherit from their parents
→ DNA (Deoxyribonucleic acid) or genes. But since it's a crossword, likely DNA.
But clue says "controls the traits" → Genes or DNA.
However, genes are more precise. But DNA is often used.
But check length — depends on grid.

Let’s look at possible lengths later.

10. Control center of the cell
→ Nucleus
✔ Answer: Nucleus

12. What is the basic unit of structure?
→ Cell
✔ Answer: Cell

Now let's fill in the crossword using these answers and check consistency.

We’ll go through each clue and place them in the grid.

But since we can't see the image, we rely on logic and standard crossword conventions.

Let’s list all answers:

Final Answers:

Across:
6. Tissue
7. Oxygen
9. Organ
11. Muscle
13. Nervous
14. Membrane
15. Cytoplasm

Down:
1. Epithelial
2. Lungs
3. Chromosomes
4. Microscope
5. Connective
8. Genes / DNA
10. Nucleus
12. Cell

Now let’s double-check some:

- Clue 8: "Controls the traits children inherit from their parents"
→ Best answer: Genes (commonly used in biology education).
If the space allows, DNA also works, but “genes” is more accurate for inheritance control.

- Clue 2: Organs — heart, brain, liver, ____, kidneys
→ Common missing one: lungs or stomach or pancreas.
But lungs is most symmetrical and common.
So Lungs is best.

- Clue 15: "Contains smaller structures that perform cell functions"
→ The cytoplasm contains organelles (smaller structures).
Yes, correct.

- Clue 14: Outer covering of a cell → Membrane (not wall — animal cells don’t have walls).

- Clue 10: Control center → Nucleus ✔

- Clue 12: Basic unit of structure → Cell ✔

- Clue 5: Anchors, connects, supports → Connective tissue ✔

- Clue 4: To study cells → Microscope ✔

- Clue 3: Thread-like structures in nucleus → Chromosomes ✔

- Clue 1: Covers surfaces → Epithelial ✔

Now, let’s consider the word lengths.

Let’s try to deduce the grid layout from clues.

But since we can’t see the image, here’s a logical way to complete it.

Let’s assume the crossword has:

- Across:
- 6: Tissue (6 letters)
- 7: Oxygen (6 letters)
- 9: Organ (5 letters)
- 11: Muscle (6 letters)
- 13: Nervous (7 letters)
- 14: Membrane (8 letters)
- 15: Cytoplasm (9 letters)

- Down:
- 1: Epithelial (10 letters)
- 2: Lungs (5 letters)
- 3: Chromosomes (11 letters)
- 4: Microscope (10 letters)
- 5: Connective (10 letters)
- 8: Genes (5 letters) or DNA (3 letters) — likely Genes
- 10: Nucleus (7 letters)
- 12: Cell (4 letters)

Now, let’s cross-reference.

For example:

- Across 6: Tissue — 6 letters
- Across 7: Oxygen — 6 letters → starts at same row as 6?
- Across 9: Organ — 5 letters
- Across 11: Muscle — 6 letters
- Across 13: Nervous — 7 letters
- Across 14: Membrane — 8 letters
- Across 15: Cytoplasm — 9 letters

Down 1: Epithelial — 10 letters → very long, likely vertical

Down 4: Microscope — 10 letters → another long one

So probably, Down 1 and Down 4 are both 10-letter words.

That matches: Epithelial and Microscope both 10 letters.

Similarly, Connective = 10 letters → Down 5

Chromosomes = 11 letters → Down 3

Nucleus = 7 letters → Down 10

Cell = 4 letters → Down 12

Genes = 5 letters → Down 8

Lungs = 5 letters → Down 2

Now, let’s build the solution logically.

Assume the grid has:

- Down 1: Epithelial (10 letters) → starts at top
- Down 4: Microscope (10 letters) → must be 10 down
- Down 5: Connective (10 letters) → 10 down
- Down 3: Chromosomes (11 letters) → longer than others

Wait — if Down 3 is 11 letters, then it must start near the top and go down 11 squares.

But the puzzle may have only 15 rows?

Looking at the clues, the highest number is 15.

So likely, the grid is around 15x15.

But without image, we proceed.

Let’s now assign answers definitively.
